March experience

I'll tell you about another experience I had in march 97.
I was travelling with my mistress. I was driving her car, while she was pressing her feet on me, on my belly, on my balls and dick, on my cheeks and in my hairs.
It was quite a sunny day after a few days of rain and my mistress was wearing black suede high heels (about 4") shoes.
I knew her soles are definitely clean because I had licked them just before getting into the car.
I hadn't lick the top of her shoes because it was clean and she didn't want to ruin the suede.
We arrived at horse riding party, where many people present and ride their horse…
There is a girl she knows, a friend of her, who is here, riding her horse. She comes to see us, after her riding. She is wearing riding outfits, with a white shirt, white trousers and black riding boots.
I notice that the boots are dirty, a bit on top but not too much, but the soles seem to be quite muddy.
My mistress notices that too. She says to her friend : "I present you my slave, he is a a very good boot cleaner. Do you want him to clean your boots ?"
Her friend doesn't know what to answer, she seems to be shy, afraid. My mistress, seeing this, says that it will be okay, she has done it many times with very dirty boots…
Finally, the girl accept my mistress' offer. I'm told to lie on my back. Then my mistress tells the girl what to do : "You stand on him, and then you push one sole on his mouth and tell him to lick it clean."
But the girl just put lightly one boot on my belly and that's all. Seeing this my mistress, decide to show her : she stands on me, press her shoe on my mouth and orders me to lick her sole clean. I do it and the girl watch me licking she sole of my mistress.
Then my mistress tells the girl to try now. The girl seems to be more sure of her, she put her first boot on my chest, then the second one. She is now stepping on me. My mistress tells her to bring her sole over my mouth, but she doesn't move and says she can't do that because her soles are covered with mud and, may be, some horse shit.
My mistress tells her that it doesn't matter, I can do it, but she doesn't move. So my mistress says she will show her.
She walk to a big horse shit. She first get some mud under her right sole, then she press her shoe into the horse shit and comes back to me.
She orders me to lick that shitty sole, and I do it. The girl is very surprised, and look at me licking the mix of mud and shit from my mistress sole.
After that, I don't feel very well, but don't say anything, and now the girl steps on me and this time she put a boot on my mouth.
So I began to lick her dirty sole (there was only mud I think), and the more I lick the more secure she is.
At the end, when I have finished, she steps in a fress mud puddle and orders me to lick her sole clean again.
